The unit is opened by removing the three screws on the back 
cover. Inside are two sets of micro-switches, a printed circuit 
board with a plug-in terminal and a jumper strap. 

With the AP25 autopilot system there are several possibilities to 
connect to other equipment for data collection and exchange. 
1. Use SimNet  
2. Use SimNet via AT10 Universal SimNet/NMEA Converter 
3. Connect to a NMEA2000 network via the adapter (drop) 

cable, part no. 24005729. 

4. The AC10 has a single NMEA0183 input/output port. 
5. The AC20 and AC40 have two NMEA0183 input/output ports 

and Clock Data interface to Simrad and Furuno radars. 

The NMEA0183 output may also drive Simrad IS15 instruments 
directly. 
The different connecting diagrams on the following pages 
illustrate the interface possibilities of the AP25 autopilot. 

The SimNet cable system with very small plugs in both ends 
makes it easy to run the cables, only 10 mm (3/8”) holes are 
required through panels and bulkheads. The SimNet accessory 
program contains the necessary items to complete a successful 
installation.
